Solubilization and coordination of the HgCl₂ molecule in water, methanol, acetone, and acetonitrile: an X-ray absorption investigation

Abstract

X-ray absorption spectroscopy (XAS) has been employed to carry out a structural characterization on the local environment around mercury after dissolution of the HgCl2 molecule. A combined EXAFS (extended X-ray...

Following a Silent Metal Ion: A Combined X-ray Absorption and Nuclear Magnetic Resonance Spectroscopic Study of the Zn2+ Cation Dissipative Translocation between Two Different Ligands

“…X-ray absorption spectroscopy (XAS) provides element-specific structural and electronic information on the local structure around a photoabsorbing atom and is applicable to both solid and solution samples. Consequently, leveraging the insight provided by XAS to investigate Zn 2+ -based systems in solution may allow one to gain valuable and unrivaled information on the reactive, structural, and electronic properties of the Zn 2+ species at play. − Moreover, the combined use of different experimental techniques to monitor the advancement of a chemical process is often a powerful tool for a satisfactory understanding of the operating reaction mechanism. XAS has been successfully coupled with UV–vis to follow chemical reactions involving nickel, iridium, palladium, and iron complexes in solution. , An alternative of this combined experimental approach is to couple XAS with 1 H NMR as both techniques can be used to investigate reactive systems containing metal ions that are impossible to measure with other spectroscopic methods.…”
